STANLEY M. SWINDALL, OF TYLER, TEXAS.

G RAVITY DU M P-CAR.

SPECIFICATION forming part of Letters Patent No. 684,127, dated October8, 1901. Application filed September 6, 1900. Serial No. 29,173. (Nomodel.)

To 62/ whom it may concern.-

Be it known that I, STANLEY M. SWINDALL, a citizen of the United States,residing at Tyler, in the county of Smith and State of Texas, haveinvented a new and useful Improved Gravity Dump-Oar, of which thefollowing is a specification.

Myinvention relates to dump-cars, and has for its object the productionof a car which shall be comparatively cheap in first cost, easilyconstructed, easily operated, not liable to become deranged, which shallbe provided with dumping-sections which can be simultoneously operated,when so desired, which shall have the load supported mainly by thestringers adjacent the axial line of the car, andwhich shall possesscertain novel and characteristic features of construction, constitutingit a superior instrumentality for performing the requisite functions.

My invention consists in certain novelties of construction andcombinations of parts hereinafter set forth and claimed.

Figure 1 is a side elevation View of approximately one-half of a carembodying my improvements. Fig. 2 is a plan view of Fig. 1 with'thedumpingsections removed. Fig. 3 is a section of Fig. 1, taken on a lineadjacent the body-bolster. Fig. 4 is a view similar to that shown byFig. 3 and illustrating the positionstaken by the sections whendischarging the load.

Referring to the several figures, the letter a designates the stringers,which are located above the trucks.

0 is an end sill; B, a body-bolster.

cl represents filling-pieces on top of the bodybolster.

F is a needle-beam.

e represents filling-pieces on top of the needle-beam.

O O are the sides, constructed substantially as shown; b, bolts passingthrough the sides and body-bolster and needle-beam and also through theends of the end sill.

D represents the dumping-sections, each comprising a floor-piece h, aperpendicular piece '5, and an oblique piece It, the said floorpiece itbeing slotted between an outside stringer and the side 0 of the car andin line with the body-bolster and needle-beam.

H represents the hinges. I is a longitudinal rod.

J represents bearings for the rod, secured to the stringers.

L is a lever suitably located.

M represents jointed locking bolts; N, guides on the bottoms of thesections; 0, straps on the sides with holes at the ends to receive theends of the jointed locking-bolts.

P represents notches made in the tops of the stringers to receive thelocking-bolts.

R represents projecting castings secured in fixed positions on thelongitudinal rod and extendi-ng at right angles thereto, and Srepresents pins by which the jointed locking-bolts are pivoted tothecastin gs upon the longitudi nal rod.

It will be observed that each section is so constructed and hinged thatwhen the section is empty the side or floor portion adjacent the outeredge of the car is of lighter weight than the part located adjacent theaxial line of the car, that by reason of this construction each sectionwhen empty will assume a horizontal position, that the car has nooutside sills, that the sections when in horizontal positions have thefloor-pieces substantially on a level with the top surfaces of thefillingpieces, that all of the jointed locking-bolts are pivoted to thelongitudinal rod, whereby both the sections can be operatedsimultaneously, and that the free portions of the sections adjacent thecar sides are located between an end sill and a body-bolster, between abody-bolster and a needle-beam, and between needle-beams. I

It is of course understood that the half of the car not shown isidentical in construction with the part illustrated by the severalfigures and that the entire car has two end sills, two bodybolsters, andtwo needlebeams, though when the car is made longer additionalneedle-beams may be used.

While I have illustrated and described only one example of the physicalembodiment of my invention, I do not thereby intend to exclude from thescope of my claims other examples which are substantially identical,being constructed for the same purpose and having a substantiallyidentical mode of operation.

\Vhat I claim is- 1. The combination in a dumping-car, ofthelongitudinal stringers; the body-bolsters; filling-pieces on the endsof the bolsters; needle-beams; filling-pieces on the ends of theneedle-beams; longitudinal sides supported by the body-bolsters andneedle-beams; and a dumping-section located each side of the axial lineof the car and hinged to an outside stringer.

2. The combination in a dumping-car, of longitudinal stringers extendingthe entire length of the car; body-bolsters; needlebeams; sidessupported by the ends of the body-bolsters and needle-beams; two slotteddumpin -sections, one on each side the central line of the car andextending practically its entire length; and means for locking andreleasing the sections.

3. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of two dumping-sections, D; a longitudinalrod; jointed locking-bolts supported in bearings on the under sides ofthe sections and operated by the revolution of the rod; and perforatedstraps located on the car sides and adapted to receive the ends of thelocking-bolts.

4E. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of two dumping-sections, D, each sectionconsisting of a slotted floor-piece, h, a perpendicular piece, 2', andan oblique piece, it; and means for locking and releasing the sections.

5. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of dumping-sections; a longitudinal rodsupported in bearings; a lever; castings, R jointed locking-bolts eachmade in two part-s and pivoted to the castings; and guides for the boltson the bottoms of the sections.

6. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of dumping-sections; hinges, H, by which thesections are secured to the stringers; and means for locking andreleasing the sections, embracing a longitudinal rod I and jointed rods,M, said rods being located within slots or notches formed in thestringers.

7. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of dumping-sections hinged to the car;sides, 0 C; perforated, straps on the sides; the longitudinal rod; aseries of castings on the rod; a series of jointed lockingbolts pivotedto the castings; and a lever; said castings and locking-bolts being inline when the sides are locked, whereby accidental unlocking isprevented.

8. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of two duinpting-sections located onopposite sides of the axial line of the car and having slotted floors;hinges securing the sections to the car-body, each section being sohinged that the part of the section adjacent the axial line of the carwill overbalance the part adjacent the car side when the section isempty; and means for locking and releasing each section.

9. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of stringers extending the length of thecar; dumping-sections located on opposite sides of the axial line of thecar 5 hinges securing the sections to the car; body-bolsters andneedle-beams; filling-pieces on the ends of the bolsters andneedle-beams; the floor-pieces of the dumping-sections, when thesections are locked, being substantially in line with the top surfacesof the fillingpieces so as to constitute or form a continuous floor onthe same level; and mechanism for locking and releasing the sectionswhich when unloaded and under the action of gravity occupy horizontalpositions on top of the stringers.

10. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of hinged dumping-sections each having aslotted floor; sides, 0 C; and means for locking and releasing thesections; the outer portions of the floors 7t, h, of the sections beinglocated between the end sill and a body-bolster, between abody-bolsterand a needle-beam, and between needle-beams.

11. The combination with a dumping-car, constructed and operatingsubstantially as set forth, of permanent sides, C 0; bodybolsters;needle-beams; filling-pieces; stringers; and hinged dumping-sections;the floorpiece of each dumping-section being slotted and closing theopen space between a side, C, and an outside stringer, and normallyunder the action of gravity occupyinga horizontal position on top of thestringers, but, when loaded, supporting the major part of the loadadjacent the side, 0.

12. Ad umping-carhaving stringers located centrally of the car only;body-bo1sters5 needle-beams; sides, 0 0, supported by the bodybolstersand needle-beams; hinged dumpingsections on opposite sides of the axialline of the car each having a slotted floor; and looking and releasingmeans for the sections; each dumping-section adapted, when empty, andunder the action of gravity, to automatically assume a horizontalposition on top of the stringers.

13. A dumping-carhavingstringers; sides, C C; body-bolsters;needle-beams; hinged dumping-sections each having a slotted door; andmeans consisting of a longitudinal rod, jointed bolts, perforatedstraps, and a lever for locking and releasing the sectionssimultaneously.
